-If your project folder is not a subfolder of the Apache document root, then your
-``<VirtualHost>`` element may need a nested ``<Directory>`` element to grant the web server access to the files.
+The above configuration assumes the project folder is located as follows:

+.. code-block:: text

+    apache2/
+       ├── myproject/      (Project Folder)
+       │      └── public/  (DocumentRoot for myproject.local)
